Clinical Trial Summary

This primary purpose of this study is the evaluation of the immunological persistence following completion of the 3-dose primary vaccination course with either a clinical or a commercial lot of pneumococcal conjugate vaccine GSK1024850A in study NCT00808444. In addition, the study will also assess the safety, reactogenicity and immunogenicity of a fourth dose of pneumococcal conjugate vaccine GSK1024850A (commercial lot) when co-administered with Infanrix-IPV/Hib at 18-21 months of age in children primed in study NCT00808444.

The primary vaccination study was conducted in Malaysia and Singapore. The booster vaccination study will not be performed in Malaysia since the pneumococcal conjugate vaccine GSK1024850A has been registered in September 2009. However, subjects in Malaysia will be offered a booster dose of the commercial pneumococcal conjugate vaccine licensed in Malaysia and Infanrix-IPV/Hib vaccine during the second year of life according to the nationally recommended regimen. Administration of the booster dose will be outside the set-up of a clinical trial. Hence no data will be collected, no blood samples will be taken in Malaysia.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Concentrations of Antibodies Against Vaccine Pneumococcal Serotypes.	Vaccine pneumococcal serotypes assessed were serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F.; Concentrations were expressed as geometric mean concentrations (GMCs) in microgram per millilitre (µg/mL).; Pneumococcal serotype specific total imunoglobuline G (IgG) antibodies were measured by 22F-inhibition Enzyme-linked immunosorbent assay (ELISA). The cut-off of the assay was 0.05 µg/mL.	Before booster vaccination at Month 0
Primary	Concentrations of Antibodies Against Protein D (PD).	Anti-PD antibodies were determined using an ELISA assay. Concentration of specific PD antibodies was determined, using a standard reference serum. The cut-off of the assay is 100 ELISA units per millilitre (EU/mL).	Before booster vaccination at Month 0
Secondary	Number of Subjects Reporting Any and Grade 3 Solicited Local Adverse Events (AEs).	Solicited AEs = AEs to be recorded as endpoints in the clinical study. The presence/occurrence/intensity of these events is actively solicited from the subject or an observer during a specified post-vaccination follow-up period.; Solicited local symptoms assessed were pain, redness and swelling. Any = occurrence of any local symptom regardless of intensity grade. Grade 3 pain = cried when limb was moved/spontaneously painful. Grade 3 redness/swelling = redness/swelling above 30 millimetre (mm).	Within 4 days (Days 0-3) after booster vaccination.
Secondary	Number of Subjects Reporting Any, Grade 3 and Related Solicited General Adverse Events (AEs).	Solicited general symptoms assessed were drowsiness, irritability, loss of appetite and fever (= axillary temperature equal to or above 37.5 degrees Celsius (°C)).; Any= occurrence of any general symptom regardless of intensity grade or relationship to vaccination Grade 3 drowsiness = drowsiness which prevented normal activity. Grade 3 irritability = crying that could not be comforted/ prevented normal activity. Grade 3 loss of appetite = not eating at all. Grade 3 fever = temperature >39.5°C.; Related = solicited symptom assessed by the investigator as causally related to study vaccination.	Within 4 days (Days 0-3) after booster vaccination.
